Bug #8644 make the cp1250_czech_cs act like latin2_czech_cs

Description:
Hello,
there is difference between collation cp1250_czech_cs and latin2_czech_cs. In my opinion, latin2_czech_cs sorts czech words more naturally, then it does cp1250_czech_cs.

Thanks
Roman Porizka 

How to repeat:

cp1250_czech_cs;
Query OK, 0 rows affected (0.06 sec)

mysql> insert into bug6610
values("s"),("S"),("sa"),("Sa"),("so"),("So"),("SO");
Query OK, 7 rows affected (0.00 sec)

Many thanks for writing a feature request.

I think this is a bug.

Here is my test case:

Environment encoding: UTF8

set names utf8;

create table t_latin2(v varchar(100))default charset=latin2;
create table t_1250(v varchar(100))default charset=cp1250;

insert into t_latin2
values
('a'),('b'),('c'),('A'),('B'),('C'),('d'),('e'),('f'),('D'),('E'),('F'),
('g'),('h'),('i'),('G'),('H'),('I'),('j'),('k'),('l'),('J'),('K'),('L'),
('m'),('n'),('o'),('M'),('N'),('O'),('p'),('q'),('r'),('P'),('Q'),('R'),

('é'),('É'),('ě'),('Ě'),('í'),('Í'),('ĺ'),('Ĺ'),('ľ'),('Ľ'),('ň'),('Ň'),
('ó'),('Ó'),('ö'),('Ö'),('ř'),('Ř'),('š'),('Š'),('ť'),('Ť'),('ú'),('Ú'),
('ů'),('Ů'),('ü'),('Ü'),('ý'),('Ý'),('ž'),('Ž'),('sa'),('Sa'),('So'),('SO'),('so'),('ch'),('CH');

insert into t_1250
values

('ů'),('Ů'),('ü'),('Ü'),('ý'),('Ý'),('ž'),('Ž'),('sa'),('Sa'),('So'),('SO'),('so'),('ch'),('CH');

SELECT * FROM t_latin2 ORDER BY v COLLATE latin2_czech_cs;

SELECT * FROM t_1250 ORDER BY v COLLATE cp1250_czech_cs;

Result:

As you can see:
cp1250_czech_cs sorts first capital letter then lower case letter and latin2_czech_cs sorts capital/lowercase vise versa.
